* libguile/jit.c (jit_alloc_fn): On targets that need a dynamically
allocated literal pool, we will need to trace that pool, so pass a
pointerful malloc. Fixes JIT on AArch64.
* libguile/i18n.c (SCM_MAX_ALLOCA): New macro.
(SCM_STRING_TO_U32_BUF): Accept an additional variable to remember
whether we used malloc to allocate the buffer. Use malloc if the
allocation size is greater than SCM_MAX_ALLOCA.
(SCM_CLEANUP_U32_BUF): New macro.
(compare_u32_strings, compare_u32_strings_ci, str_to_case): Adapt.
* libguile/strings.c (SCM_MAX_ALLOCA): New macro.
(normalize_str, unistring_escapes_to_r6rs_escapes): Use malloc if the
allocation size is greater than SCM_MAX_ALLOCA.
* test-suite/tests/i18n.test, test-suite/tests/strings.test: Add tests.
Previously, 'put-u8' used textual I/O to write a single character,
relying on the usual practice of setting the port encoding to ISO-8859-1
for binary ports.
* libguile/r6rs-ports.c (scm_put_u8): Use 'scm_c_write', not 'scm_putc'.
* libguile/numbers.c (scm_exact_integer_sqrt, scm_sqrt)
(exact_integer_is_perfect_square, exact_integer_floor_square_root):
Where it is trivial to do so, use GMP's low-level mpn functions to
avoid heap allocation.
This reverts the change to SCM_MAKE_CHAR made in the previous commit
63818453ad, which used an arithmetic trick
to avoid evaluating its argument more than once.
Here, we restore the previous implementation of SCM_MAKE_CHAR, which
evaluates its argument twice. Instead, we introduce a new inlinable
function 'scm_c_make_char' and replace uses of SCM_MAKE_CHAR with calls
to 'scm_c_make_char' where appropriate.
* libguile/chars.h (scm_c_make_char): New inline function.
* libguile/inline.c: Include chars.h.
* libguile/srfi-13.c (REF_IN_CHARSET, scm_string_any, scm_string_every)
(scm_string_trim, scm_string_trim_right, scm_string_trim_both)
(scm_string_index, scm_string_index_right, scm_string_skip)
(scm_string_skip_right, scm_string_count, string_titlecase_x)
(string_reverse_x, scm_string_fold, scm_string_fold_right)
(scm_string_for_each, scm_string_filter, scm_string_delete):
Use 'scm_c_make_char' instead of 'SCM_MAKE_CHAR' in cases where the
argument calls a function.
* libguile/chars.c (scm_char_upcase, scm_char_downcase, scm_char_titlecase),
libguile/ports.c (scm_port_decode_char),
libguile/print.c (scm_simple_format),
libguile/read.c (scm_read_character),
libguile/strings.c (scm_string_ref, scm_c_string_ref),
libguile/vm-engine.c ("string-ref"): Ditto.
* libguile/jit.c (compile_ursh_immediate):
(compile_ulsh_immediate): Fix immediate/register variant calling.
Happily a benefit of lightening, as type safety did this for us.
(DEFINE_CLOBBER_RECORDING_EMITTER_R_R_2): Pass JIT state.
* libguile/programs.c (scm_i_program_name): Use scm_i_primitive_name for
primitives. No functional change though.
* libguile/vm.c (DEFINE_BUILTIN): Mark builtins as primitives.
* libguile/jit.c: Operands have their ABI in them. We can now have
addends on GPR and MEM operands, which can improve register
allocation. Use new jit_calli_3, etc helper APIs.
The motivation for this change is that SCM_MAKE_CHAR is sometimes passed
an expression that involves a procedure call that is not always trivial.
In other cases, the results are not guaranteed to be the same both
times, which could lead to the creation of invalid SCM objects.
* libguile/chars.h (SCM_MAKE_CHAR): Reimplement.
